BEOWAVE

Home Bluetooth speaker

A working omnidirectional Bang & Olufsen speaker made from existing speaker parts made from 20lb foam. A working omnidirectional Bang and Olufsen speaker made from Doss speaker parts made from 20lb foam. 

14 week project / brief: Design a Bluetooth speaker from DOSS speaker parts using tools available in the ArtCenter model shop/ skills: form development, fabrication

Beowave.1 Beowave.5

What I learned

I learned to create a working prototype of a speaker. I learned how to take into account the acoustics of a speaker while designing. I learned how to use basic shop tools such as the mill, band saw, table saw, drill press, and belt sander. I learned how to spray paint with a paint gun and create a smooth coat of paint.

Ideation Sketches

I came up with many pages of ideation and decided to make cardboard prototypes of the Omnidirectional form and Double form.

Figuring it out

I chose the omnidirectional speaker due to its more luxurious form that fit more with the Bang & Olufsen brand. I made a few prototypes with black foam, MDF, and dowels, to see which proportion and alignment would work best. I made an initial 10 lb foam prototype to see how the DOSS speaker parts might fit in.

Fitting Parts

I fit the DOSS speaker parts into a more refined 10 lb foam prototype. The drivers and passive radiators are pointed towards the cone to project the sound outwards into the room.

Fabrication

I routed out space to fit passive radiators and drivers at the bottom of the top assembly. I made an acrylic encasing for the aux PCB board and used bondo to fix it onto the foam. I sanded down the foam encasing before priming the speaker. Upon priming, I realized the primer gave parts too much volume, so things no longer fit. I sanded it down so everything fit. I spray-painted all the parts before attaching the electrical components. 

Final Assembly

Final painted parts, assembled subassemblies, and final touches.
